Are you checking at the alternator output stud?

By putting in higher power headlights, you've increased the current draw
from the alternator. If it's tired, you may be pushing it hard enough that
it can no longer keep up... as always, pull the regulator and check the
brushes before pulling the alternator, they are a wear item.
